With the introduction of native-to-EVE market APIs, the EMDR project has ran its course. As of May 1, 2017, we have shuttered the network. This repo will remain in an archived state. Thanks to all who helped make EMDR a success!

EVE Market Data Relay (EMDR) is a super scalable, highly available firehose of
real-time market data. For those that wish to record price and history data
as it comes in, EMDR will help you do so as efficiently and reliably as
possible. EMDR’s data feed is open to the public, and is developed as an
open source project.

EMDR may appeal to you if:

You need real-time access to market data, as soon as possible. Perhaps for
sending out price/inventory level alerts, notification of lucrative
trade routes, or real-time charts and graphs.

You want to record prices over time.

You want the absolutely most complete set of data that you can get.

The effort and overhead of getting large amounts of direct player uploads to
your site is too much to bear.

EMDR’s primary goals are:

Ensuring that all market sites have access to player-uploaded market data.
